SPECIFICATION forming part of Letters Patent No. 413,828, dated October 29, 1889. Application ala January 28, 1287. serai No. 225,822. (No model.)

Be it known that I, JAMES A. MARSH, a citizen'of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor Burners and Stoves, of which the following is a description.

My invention relates to vapor burners and* stoves; and it consists ofthe improvements hereinafter described and claimed.

My improvements are illustrated in the accompanyingdrawings, in whichf- Figure 1 is a side view in elevation; Fig. 2,

Aa cross-section, partlyin elevation, and showinga modification of the burner-cap; Fig. 3, a perspective view of the modified burnercap; Fig. 4, a front elevation of the central burner; Fig. 5, a planwiew of same with burner-cap removed, Fig. 6, a horizontal section on line x of (Fig. 2; Fig. 7, a sectional view of an oven` and connections with my burner attached; Fig. 8, a transverse section of same, showing opening in the side for heat; and Figs. 9, 10, and 1l, detail views of modifications of lighting-'tube as shown in Fig. 1. V-

Referring to the drawings, A is an oven attached to one side of a gasoline-stove to be heated by a burner D. Y

K is a burner composed of. the retort or vaporizing-chamber G and burner-chamber F.

The burners D and 8 are non-generating Pis a pipe for supplying gasoline from any suitable reservoir to the vaporizingchamber G through stand-pipe H. Y

VE E are'pipes for supplying, through intermediate pipes l and 2, the burners D and 8 with thel generated vapor from the' chamber G. Ignited gas may also be carried from burner D to burner K, or vice versa, through pipes C C2; and E is a valve in pipe E for controlling said supply.

3 is a valve controlling the gas in pipe l, leading to the burner D,and t is a valve con- A, trolling thegas in pipe 2, leading to'burnerv S. At the point y, where the valve 4; is located, the pipe F. receives its supply of vapor from generator G.

The generating-chamber G is composed of two vcompartments g. g2, and is connected vwith supply-pipe H as follows: h is a duct leading from the top of pipe H and at right angles therewith to compartment g', and is controlled by valve H. h2 is a duct leading off from pipe H in the same direction as hvbut below it, and connects with duct t', which leads down to channel 724, leading into a drip-cup h5. The duct t' and channel 7i* are controlled by valve h3. Connecting with compartment g2 is a duct g2, leading down into cross-pipe g4, which connects with a needle-jet oriiicef in pipe gwhich extends up and crosses duct g3 at right angles therewith and is controlled by valve 6.

The burner-chamber F is provided with a perforated bottom f3 and with a downwardlyprojecting tube f4.

the tubef2, which in turn is supported by' disk G2. G2 projects out from and is a part vof the generating-chamber G, and through which tube f2 extends. The tube f2 is secured tightly to a downwardly-p rojecting part of G2 by means of a set-screwf.

C is a pipe provided with a branch C2, terminating at one end in proximity to burnerchamber F and at the other end in proximity to burner D, for the purpose of conducting ignited gas `from said chamber to the said burner. The pipe C on its Way to chamber F passes through opening cel in disk G2. C is a similar pipe for conducting ignited gas from burner K to burner 8, and 9 is a hanger for supporting, pipe C.

In Fig. 10, at the point where the pipe c2 crosses the large induction or vapor tube F., a valve is placed controlling a duct c4, leading from tube E into lighting-tube c2 for controlling the inlet of gas from tube E into tube c2, whereby gas may be thrown both ways through tube c2 for automatically lighting either burner D or K.

As shown in Fig. 11, c5 is a small pipe enn tering commingling-chamber 7 of burner 8 and extending into and to near the Acenter of the tube C for the purpose of facilitating the action of automatic lighting of burner S by burner K by projecting a small portion of unlighted gas from the'commingling-chamber IOO of burner K against the llame in the lightingtube. In order that flame ignited at the end of pipe c5 shall not flash back into commingling' chamber 7, the hole through said pipe should be exceedingly small-not larger than one-sixteenth of an inch in diameter, and preferably smaller. I have found that with such a small pipe the flame will not flash back.

The oven A may be of any of the well-known forms of oil, gas, or gasoline ovens, and can be placed at either end or at the back of the stove.

A2 is the top of the stove, and beneath this top I place a bottom plate B, which surrounds the burner K and forms a ilue b. A corresponding opening b3 is formed in the side of the oven. Then a solid lid b2 or a large vessel is placed over the burner, the heat from burner K may not only be utilized for cool;- ing, but also be used to furnish additional heat to heat the oven. Currents of heat a and a2 from burner I) and from burner K will then ascend through the oven-top a3.

The operation of the stove is as follows: For initial starting, iluid being admitted to pipe I flows through stand-pipe lI to duct h2, (the duct 71, leading to vaporizing-chamber G, being closed by valve HQ) thence down pipe z' and through channel h4 into drip-cup h5. After the drip-cu p is provided with asuiiicient quantity for ignitin g, the supply thereto is cut off by turning valve 7a3, and the Vapor in the drip-cup is ignited. The generatiiig-chamber G is then heated to a Vaporizing condition. Valve II is then opened, which lets the gasoline in from pipe II to duct 7L', and thence it passes, first, into compartment g', thence into g2. There vaporized, it passes down duct g3, and,valve G being opened, it is let through needle-oriiicef into bu rnertubef2, and thence into burner-chamber F, where it is ignited. After the vapor is generated in chamber G it is distributed to non-generating burners D and 8 through the pipes E and E', respectively, as already described. Ignited gas is distributed to burners D and 8 from burner K by means of pipes C, C2, and C', as also previously described.

It will be noticed that by my arrangement of parts the llames from the burner-chamber F are all projected down through its perforated bottom onto the generating-chamber G and that the latter is so constructed with-its compartments g g2 that the fluid is compelled to pass beneath the flames of the burner-chamber twice before reaching the downward duct g3, thus utilizing to the best advantage4 the heat from the burner-chamber to maintain the vaporization in chamber G. It Will also be noticed that by reason of the independent ducts to the generating-chamber and to the drip-cup, controlled by independent valves, the act of supplying the drip-cup does not necessitate the opening or closing of the separate burners, and that all the burners maybe controlled in their supply of gas or generated vapor by one valve, so that when one burner is extinguished all may be extinguished.

By my construction and arrangement of parts burners located at different elevations on horizontal and perpendicular pipes can be lighted at one operation-a very important and material feature of my invention, as it has generally been regarded as impracticable to carry the ignited gas through pipes turned at an angle to each other and to burners at different heights. Further, the operation of the igniting-tnbe leading to such burners is greatly facilitated by the employment of the small tube to project vapor into the midst of the lighting-tube, as it replenishes the flame at that point,which otherwise might bc weakened by the long and tortuous course it would be subjected to in long con nccted horizontal and perpendicular pipes.

That I claim isl. In a Vapor-stove, in combination with two or more burners, one of said burners being provided with a commingling chamber, a pipe for carrying ignited gas from one burner to the other, and a pipe c, leading from said commingling-chamber into said gas-pipe for carrying into the latter unignitcd gas, as and for the purpose described.

2. In a vapor-stove, in combination with two burners, an induction or vapor tube for carrying the vapor from one burner to the other, a tube for carrying ignited gas from one of said burners to the other, a duct leading from said Vapor-tube into said lighting-tube, and a valve controlling said. duct, whereby gas may be thrown to both burners, substantially as described.
